OIL-BURNER.

Application filed June 28,

To all whom it may concern:

Be it known that I, ALVA ARTHUR LIND- LEY, a citizen of the United States, and a resident of Spokane, in the county of Spokane and State of lVashington, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

My invention relates to improvements in fuel oil burners in connection with hot water and steam furnaces or the like, whereby fuel oil may be effectively burned with efliciency. The purpose of the invention is to provide a self-cleaning fuel oil burner so'constructed as to prevent or alleviate clogging, but which is provided with means for cleaning the same out with steam or hot water in case of necessity; to provide means whereby the re ulation is automatic, according to the temperature of the heating plant; to provide means for maintaining the burner proper sufiiciently heated at all times to facilitate gasification and burning of the oil; to obviate the necessity of supplying steam or hot water continuously to the oilfor the purpose of burning the same, or forcing air thereto under pressure, and to permit the handling of all grades or mixtures and thicknesses of oil at different temperatures without changing the burner or nozzle.

A further object of the invention is to provide a fuel oil burner employing gravity instead of pressure operated feeding means, said burner being of simple and novel construction and provided with a hinged cover or flap door automatically operated in accordance with theheat generated to regulate the operation of the burner, while also permitting the parts to be easily cleaned and at the same time producing a device which can be very economically produced and; maintained in good working order.

Other and further objects of my invention will become apparent to persons skilled in the art, from a consideration of the following description when taken inconjunction with the accompanying drawings, wherein:

Figure 1 is a fuel oil burner.

Fig. 2 is a detail perspective view of the burnerproper with the cover or cap thereof removed. 7

Fig. 3 is a detail view showing the device" plan view of my improved Specification of Letters Patent.

connected for automatic operation or regulation in a steam heating plant, and

Fig. 4 is a similar view showing means for automatically regulating the position of the cover according to the temperature of the Water in a hot water heating plant.

As illustrated in the drawings, in which like reference characters designate corresponding parts throughout the several views, the improved burner consists of a burner body or nozzle 5 of substantially relatively fiat rectangular formation having a sloping portion 6 at the front portion of the top thereof, preferably formed with ears or the like 7 at either side of a central recess 8 for attachment of a flap door or hinged cover 9 which is normally held closed through the medium of springs or the like 10 engaged at the hinged connections 11 thereof. Extending longitudinally of the body is an orifice or-passage 12 which terminates at the recess 8 in a flaring mouth portion or nozzle 13 having an inclined bottom wall and diverging tapered side walls, aS clearly shown in Fig. 2 of the drawings The passage 12 extends medially of the upper portion of the burner body, and extending transversely across the lower portion of the bodybeneath the passage 12 is a passage 14 from which extend at right angles thereto and parallel to each other, a pair of pilot burner orifices 15 which communicate with the front edge or end of the burner body. Extending from a suitable source of fuel oil supply is a tube or pipe line 16, said fuel line being connected with a reservoir or tank containing oil which may be supplied with air'under pressure if desired. This pipe is connected to the opening 12 and has interposed therein, a valve 17. Between the valve 17 and the burner is interposed a .valve'18, while arranged between the valves 17 and 18 and nearer the former, .is a connection or from a source of steam or hot water supply which may be connected to a steam or hot water. heating system in connection with which the device'is'used. The pipe 19 is provided with a valve 20 by means of which the supply of hot water or steam is controlled and between the pipe 19 and the valve a pipe or tube 21 for the pilot burners or lights, the same being preferably of. curved or arcuate formation extending pipe 19 leading supply the oil to into the opening or passage 14 in the burner proper. This pipe is provided with a valve 22 by means of which the supply 011011 to the pilot burner may be effectively regu- 5 lated.

Thus, it will be seen 111 the operation of the burner, the valve 17 is opened whilethe" be slightly out off; Ofcourse,the flap door or cover 19 is opened manually, or automatically to permit the oil exuding fromthe burner to be ignited and ,thejheat from; the pilot burner will facilitate, gasification, thereof,

20 in order to produce anintense; heat The cover 9 is provided with, suitable-means; designated at 23 by which connection is made to a suitable lever. 24 automatically operated by'a diaphragm regulator 25 01 a thermostatic regulator 26 as preferred in practice, to open or close thegate or cover inthe burner as the steam, lncreases" or de creases in pressure or as the hot waterof the heating system increases; or decreases in: 30 temperature,

thereby making an automatic self-cleaning burner, although the latter can be operatedby hand if the-regulatorbecomes inoperativefor any reason. V i l Of course, it is to be understood that the pilot light burns all the tiine,andby provide ing two of the burner passages or nozzles, it is insured that one at least shall be 'open so that when thelmainburner is opened by the regulator, the same willbe instantly lighted 40 because'of the temperatureto which'th'e same has been raised by the heat thus applied. Furthermore, in the eventthatthe burner becomes cloggechthe valves117 and 22 are closed, while openingthe valves 18 1 and20,

thus allowing the pipe to be blown out or. the hot cleared, as well as the-burneryby water or steam' forcedtherethrough under pressure. Should the pilotburners become clogged, the valves 17 and 18are closed and the valves 20 and 22opened-,'thus permitting:

the steam or water to be forced through the pipe 21 and through the nozzles 15 to elfectivelyclean out the pilot burner'nozzles. Whenthe device is in operation, the valve 17 isopened to: the fuel tank -and alsothe valve 18, while the valve 20 maybe slightly opened if desired) The valve'22'isi'also set at the proper degreebfppeningu-tO allow the pilot burner to continuously operate for keeping the burner body warm and forignit-fl ing :the same if. desired, regulation, being eflt'ected saszheretofore-specified; I do not thesloping tuting the burner, including the burner body and hinged cover or gate forthe burner which is so'shaped as to form an elongated outlet end between the cover and bottom wall-of the orifice, thus eliminating in connection with the automatic regulation, the liability of clogging experienced by round orifice burners. Furthermore, the device canvbe readily and effectively cleaned out and no air pressure is used to force the fuel oil through the burner, gravity being employed ,forthis purpose, owing to the pre-heating of theoil by the pilot burners. While the tank or reservoir maybe suppliedwith air, u-nder'pressure, this is not essential to the use of the present device as in connection with round orifice burners owing to a the difficulty experienced in obtaining the proper temperaturerand which in connection withthe roundorifice burner, results in a moisture deposit in the fuel oil which finds its :way into" the jet, thus causing the clogging, of the burner; While I do notdesire to be limited to the use of any particular material, the parts are preferably constructedof brass or 4 copper, or may be made of iron with the connections made oil-tight. The device will handle all grades, or mixtures andthicknesses of'oil of different temperatures Without changing the burner or nozzle and without clogging;

In viewof the foregoing, it isthought that the operation of the devicewill be readily understood and inview of the simplicityyand practical value 1' that, it will commend itself to those skilled in the art. w 7
